Tripoli , Libya -LRB- CNN -RRB- -- The head of Libya 's opposition government told reporters Saturday he welcomed a call Friday by Russian President Dmitry Medvedev for Moammar Gadhafi to step down .

Medvedev 's statement , echoing the stance of American and European leaders , appeared to indicate a closing diplomatic window for the longtime Libyan strongman .

The chairman of the National Transitional Council , Mustafa Abdul Jalil , said he has offered amnesty to Gadhafi loyalists who defect before the demise of the regime , but reiterated that there will be `` no negotiation for any solution until Gadhafi 's departure . ''

Once that happens , elections and a constitutional referendum will be held within a year , Jailil said in the opposition stronghold of Benghazi .

In an interview with CNN , Jalil said the council had sold a shipment of oil to China for $ 160 million . The confirmation of the sale is expected to buttress the political and economic credibility of the fledgling rebel power .

The leader said the movement has a `` financial crisis '' and is seeking loans from outside the country .

The council is happy for political support , but will not ask Russia for arms or economic aid , Jalil said .

The unrest in Libya has persisted for months as opposition members demand an end to Gadhafi 's nearly 42-year rule .

Jalil marked the 100th day of the nation 's civil war .

`` We see victories emerging at both national and international levels , '' he said . `` We should celebrate what our heroic sons have accomplished in Misrata and the Nafusa mountains , as well as applaud the wide international support for our revolution . ''

Meanwhile , a series of morning explosions rocked the capital of Tripoli on Saturday , including blasts at a compound belonging to Gadhafi and one at a nearby tribal compound , a government official said .

The official said one morning strike occurred on Bab bin Ghashir , a tribal compound near Gadhafi 's Bab al-Aziziya compound , where the other strikes occurred . The official believed the strikes were NATO attacks .

No casualties were reported .

Morning strikes in Tripoli are rare . NATO confirmed one of the attacks -- a press officer said the strike on Bab bin Ghashir was timed to minimize civilian casualties .

NATO said it targeted a vehicle storage area at Bab bin Ghashir .

The tribal compound is used by people who volunteer as support forces for Libyan authorities . A decade ago , the site was used as a military station .

NATO is operating under a U.N. Security Council resolution authorizing the use of any means -- with the exception of foreign occupation -- to protect civilians from attack or the threat of attack . It has been conducting airstrikes targeting Gadhafi 's military resources .

CNN 's Amir Ahmed , Raja Razek , Nima Elbagir and Ben Wedeman contributed to this report .
